Grid and Fluid
Introduction
An Autograph field can be a Grid column, for a signature on each row (each attendee, each witness), or a field inside Fluid. Choose Autograph as the column's or the field's type, and it has the same settings as an ordinary Autograph field.
Each row or Fluid field gets its own pad. Rows and fields added on the page start their pad straight away, in the control panel and in Channel Forms.
Displaying them
Inside a Grid's variable pair, or a Fluid field's, the column or field works with the same template tags:
templates/default_site/events.group/attendees.html
{exp:channel:entries channel="events" limit="1"}
{attendees}
<div class="attendee">
<p>{attendees:name}</p>
{if attendees:signature}
{attendees:signature alt="Signature"}
{/if}
</div>
{/attendees}
{/exp:channel:entries}
